$100 Answer from H2
Zero
$200 Question from H2
Unbalanced forces acting on an object will
cause what?
$200 Answer from H2
An object to start moving, stop moving or
change direction
$300 Question from H2

acting on an object.
$400 Answer from H2
Answers will vary
$500 Question from H2
When showing forces on a diagram, larger
arrows mean what?
$500 Answer from H2
A larger force is being exerted
$100 Question from H3
In the sticky sneakers lab we were testing
for what force?
$100 Answer from H3
friction
$200 Question from H3
How does direction of friction compare to
direction of motion?
$200 Answer from H3
It is acting in the opposite direction
$300 Question from H3
The strength of the force of friction depends
on what 2 factors?
$300 Answer from H3
How hard the surfaces push together and
the types of surfaces
$400 Question from H3
What are 2 ways I can decrease friction a sled
experiences?
$400 Answer from H3
Wax the sled or change the mass on the sled
$500 Question from H3
What are the 4 types of friction?
$500 Answer from H3
Static, sliding, rolling, fluid
$100 Question from H4
What is weight?
$100 Answer from H4
A measure of the force of gravity on an object
$200 Question from H4
In free fall is the force of gravity balanced out
by another force?
$200 Answer from H4
No, gravity is the only force acting on the
object
$300 Question from H4
What is the force of gravity at or near the
Earth's surface?
$300 Answer from H4
9.8 m/s²
$400 Question from H4
What are 2 forces that affect gravity?
$400 Answer from H4
Mass of the objects and distance between them
$500 Question from H4
What is the difference between mass and
weight?
$500 Answer from H4
Weight changes due to the force of gravity
mass does not
$100 Question from H5
What is motion?
$100 Answer from H5
An object is in motion if its distance from
a reference point is changing
$200 Question from H5
What kind of force changes an objects
motion?
$200 Answer from H5
An unbalanced force
$300 Question from H5

$400 Answer from H5
Terminal velocity
$500 Question from H5
If you know the mass of an object in kg how
do you determine it's weight on Earth in
newtons.
$500 Answer from H5
Multiply it's mass in kg by the measurement of
Earth' gravity(9.8 m/s²)
